Use dc motor controller, can appear sometimes cannot be started, and cause a variety of reasons for this. Below small make up to introduce for everybody. 1. Lack of power supply: due to the power switch didn't together, before the fuse fusing, motor controller of main circuit and control circuit fuse fusing causes such as its cannot be started, so we can start by level before the fuse, slowly to the motor controller all the parts of the main circuit and control circuit conductor and the device to find out the reason and repair. 2. Motor controller failure: because of the brush wear serious, get stuck, the reason such as the spring pressure is not enough, so we can disconnect the power, using a multimeter to test the resistance, find out the problem and repair. Above is the introduction to dc motor controller cannot be started, you understand?
